Abstract: The X80 φ1219mm×18.4 mm HSAW pipe and welding auxiliary materials including filler metal and flux used for X80 steel are developed for the urgent need of the Second West-East Gas Pipeline Project. Low carbon and high niobium alloy system has been applied to the new product, and mass industrial production of hot-rolled coils with 18.4 mm (WT) has been realized. The HSAW pipe conforms to Q/SY GJX 0102-2007 "Technical Specification of HSAW Pipe for the Second West-East Gas Pipeline Project", and it has now been applied to the Second West-East Gas Pipeline Project.

Key words: X80, high Nb steel, mechanical property, HSAW pipe, the Second West-East Gas Pipeline Project
